Why is it every time a scientific paper is posted to HN the first few comments point out the tired "correlation != causation" or some other catch phrase? It's a peer reviewed paper, by actual researchers and scientists. I'm 99.99% sure they are aware that correlation isn't causation. Furthermore, nowhere in the abstract does it draw any conclusions at all, it merely gives the results. The only people drawing conclusions are you and the other people posting tired cliches.
